2 Claims.

to provide a runway or chute through which the coin will pass before itis deposited into the mechanism which it is to render active.

It is one of the objects of the present invention to provide improvedmeans, preferably in proximity to the entrance opening of the chute, forseparating or detecting the coins or tokens that are deposited thereinso that improper ones will be arrested and prevented from travelingthrough the runway, but which arresting means will not interfere withthe passage of proper coins or tokens through the chute.

A further object is to provide improved means for retaining the impropercoin or token in proximity to the entrance opening of the chute, andimproved means whereby the coins or tokens thus retained may be engagedby an implement and passed back through the receiving opening, to bereturned to the operator.

To the attainment of these ends and the accomplishment of other new anduseful objects 1- as will appear, the invention consists in the featuresof novelty in substantially the construction, combination andarrangement of the several parts hereinafter more fully described andclaimed, and shown in the accompanying drawing illustrating thisinvention, and in which:

Figure 1 is a detail view in elevation of the en trance portion of thecoin slot or chute.

Figure 2 is a detail sectional view taken on line 2-2 Figure 1.

Figure 3 is a detail perspective view, partly in section, of a portionof the coin chute.

Figure 4 is an enlarged detail sectional view taken on line 4-4 Figure11 Figure 5 is an enlarged sectional view taken if:

on line 55 Figure 4.

Figure 6 is a view partly in elevation, partly in section, and partlybroken away, of another form of coin chute.

Referring more particularly to the drawing, the so numeral I0 designatesgenerally a runway or chute along which the coins are adapted to travel,the runway being provided with a bottom H.

A magnet I! (Fig. 2') is arranged adjacent one of the sides of therunway to create a magnetic field through which field the coin or tokenI3 is to pass as it passes down the runway, the pole or free ends of themagnet passing through suitable openings of the wall of the runway.

This runway is preferably arranged in an inclined position and isprovided with an entrance opening [4 and arranged in alinement with thisopening is a coin receiving slot l5 which has communication with saidentrance. The entrance slot i4 is preferably arranged in an inclinedposition although if desired it may be arranged uprightly. A magnet I6is held in position in any suitable manner such as by means of a band orstrap I! anchored at its ends, as at IS.

The poles or free ends I 9 of the magnet project through suitableopenings in the wall of the entrance slot I4 and this slot 14 isprovided at its bottom with a shoulder 20 having an inclined or beveledportion 2|, so that when the coin l3 which is of a proper denominationand characteristic is inserted in the slot l5 it will strike and bedeflected by the inclined portion 2| into the entrance opening M of thechute or runway.

When, however, a token or slug 22, which is of an improper value orcharacteristic, is deposited into the slot I5, if such slug is of ametallic construction, it will be attracted by the poles or ends l9 ofthe magnet so that the periphery of the slug will engage and rest uponthe shoulder 20 and the slug will thereby be prevented from passing intothe entrance opening M of the runway and will be maintained in thisposition.

In these circumstances, should it be attempted to dislodge the slug 22from the magnet M5 by the insertion of other tokens or by an implementinserted into the slot I5 in an attempt to force the slug 22 downwardlyinto the runway H), the shoulder 20 upon which the slug rests willprevent such operation, due to the fact that the magnet #6 will hold theslug in a position that it will rest upon the shoulder 20.

In the event that such a slug is inserted into the slot I 5, and inorder to remove the same, there is provided a slot 23 in the casing wall24, a portion of which slot is in alinement with a slot 25 that passesthrough the shoulder 20 and also the inclined portion 2| thereof.

With this arrangement when the slug 22 is held adjacent the magnet 16 animplement may be inserted through the slot 23 below the slot 25 in theshoulder 20, and then by raising the implement so as to move the sametoward the other end of the slot 23, the end of the implement will passthrough the slot 25 and engage the edge of the slug 22 and raise thelatter, forcing the same along the magnet l6 so as to project the slug asufiicient distance beyond the entrance of the walls of the passagewhich permits the Y insertion of an implement to remove the coin 28which has adhered to the magnet IE, or which is held within the slot,conforms to the configuration of the passage 26, a portion of the slot2'! being in register with the slot 25 through the 5 shoulder 20 so asto permit the implement to be inserted beneath the lowermost edge of thecoin or token. By then manipulating the implement to raise the coin andpass it back through the passage 26 it will be returned to the operator.

been herein shown and described, it is to be understood that variouschanges may be made in the details of construction and in thecombination and arrangement of the several parts, within the scope ofthe claims, without departing from the spirit of this invention.

What is claimed as new is:

1. Detecting mechanism for coin and like meelement through the passage,a portion of the said shoulder being beveled to deflect predeterminedelements past said shoulder and into the passage, and a permanentlystationary magnet in proximity to said shoulder and operating to holdother predetermined elements in alinement with said shoulder, wherebyupon insertion of another coin into said passage, the coin held by themagnetic means will be caused to abut said shoulder, there being a slotin a wall of said mechanism and an opening through said shoulder andthrough which slot and opening an implement may be inserted to engageand force out of the entrance of said passage, the said ele ment whichhas been retained in engagement with said shoulder.

2. Detecting mechanism for coins and like metallic 'disc shaped elementsembodying an element receiving passage of substantial length, a shoulderformed in said passage in the path of movement of an element through thepassage, a portion of the said shoulder being beveled to deflectpredetermined elements past said shoulder and into the passage, and apermanently fixed and stationary magnet in proximity to said While thepreferred form of the invention has shoulder and operating to hold otherpredetermined elements in alinement with said shoulder, whereby uponinsertion of another coin into said passage the coin held by the magnetwill be moved against said shoulder and maintained tallic disc shapedelements, embodying an element receiving passage of substantial length,a portion of one of the walls being shaped to form a shoulder in thepath of movement of the said against further advancement in saidpassage, there being a slot in a wall of the passage, and an openingthrough said shoulder and said beveled portion for the passage of animplement to engage under the edge of the coin to move the latterbackwardly in said passage.
